Will I be required to pay capital gain tax on a property that i was quit claim deeded with right of survivorship and listed as joint tenant. How do I determine amount.

I was added to the deed in 2019 - market value of property was $97,000. Grandfather passed away in 2025 - home is being sold for $120,000. I'm trying to determine how much I will be required to pay for Capital Gains Tax. I will fall into the 15% bracket for capital Gains.
